Chrissy Teigen strips down for cover of 'Women's Health UK'

The 29-year-old supermodel goes fully nude for the cover of Women's Health UK's Naked Issue, wearing a big smile with her hands strategically placed over her breasts. But while Chrissy of course looks fantastic sans clothes, the always candid star admits her slim body takes work.

"I've always had to watch myself," Chrissy says. "My family is not naturally thin and we put on weight quickly. I find low-carb works for me. Even when I eat healthy grains like quinoa I keep them to a minimum."
